Aunt Mazie challenge.
http://mathforum.org/clime/auntmaze3.gsp
How might asking a nonalgebraic solution lead to illuminating the algebraic
solution?
Here's the problem as posted on the sketchpad file.
Birthday Trip
Jade's family is planning to travel to her Aunt Mazie's house to celebrate Aunt
Mazie's 102nd birthday. On the first day of the trip they'll drive halfway there
and then stop to set up camp for the night. On the second day of the trip
they'll drive twothirds of the remaining distance before stopping for some
sightseeing and camping. On the last day they'll have 145 miles left to drive.
Question: How far is the trip to Aunt Mazie's house?
Use the sketchpad "manipulatives" to help you solve the problem without using
Algebra. Then explain your strategy.
